,Q1. A patient with a history of hypertension and type 2 diabetes mellitus is found to have a serum creatinine
of 2.2 mg/dL and an estimated glomerular filtration rate (eGFR) of 28 mL/min/1.73 m². Urinalysis shows 2+
protein, 1+ blood, and no casts. Renal ultrasound reveals bilateral small kidneys with cortical thinning.
Which of the following is the most likely diagnosis?
A. Acute tubular necrosis
B. Rapidly progressive glomerulonephritis
C. Chronic kidney disease due to hypertensive nephrosclerosis
D. Polycystic kidney disease
Correct Answer: C. Chronic kidney disease due to hypertensive nephrosclerosis
Rationale: The patient has a long history of hypertension and diabetes, with an eGFR <30, small kidneys, and
cortical thinning, indicative of chronic kidney disease. Hypertensive nephrosclerosis is a common cause of CKD in
patients with long-standing hypertension, often presenting with proteinuria and small kidneys. Acute tubular
necrosis typically presents with acute kidney injury and normal-sized kidneys. Rapidly progressive
glomerulonephritis often has active urine sediment with red blood cell casts. Polycystic kidney disease shows
enlarged kidneys with cysts.
Why Wrong:
A - Acute tubular necrosis would present with acute onset and normal or enlarged kidneys, not small kidneys
with cortical thinning.
B - Rapidly progressive glomerulonephritis typically has active sediment with dysmorphic red blood cells and
casts, not just bland proteinuria and blood.
D - Polycystic kidney disease is characterized by enlarged kidneys with multiple cysts, not small kidneys.

Q2. Which of the following best explains the mechanism by which angiotensin-converting enzyme inhibitors
(ACEis) reduce proteinuria in patients with chronic kidney disease?
A. Inhibition of aldosterone secretion leading to decreased sodium reabsorption
B. Reduction of intraglomerular pressure by dilating efferent arterioles more than afferent
C. Blockade of angiotensin II-mediated vasoconstriction of the afferent arteriole
D. Increased renal blood flow due to systemic vasodilation
Correct Answer: B. Reduction of intraglomerular pressure by dilating efferent arterioles more than afferent
Rationale: ACEis reduce proteinuria primarily by dilating the efferent arteriole more than the afferent, thereby
reducing intraglomerular capillary pressure. This decreases the filtration of proteins across the glomerular
basement membrane. Option A is partially true but not the primary mechanism for proteinuria reduction. Option C
is incorrect because angiotensin II constricts efferent arterioles more than afferent; blocking it dilates efferent.
Option D is not specific to proteinuria reduction.
Why Wrong:
A - While aldosterone inhibition contributes to sodium and water loss, it is not the main mechanism for
reducing proteinuria.
C - Angiotensin II constricts efferent arterioles; blocking this results in efferent dilation, not afferent.
D - Increased renal blood flow may occur but does not directly explain the reduction in proteinuria.

11th Ed.
Q3. A patient with end-stage renal disease on hemodialysis develops severe muscle cramps during a session.
Which of the following interventions is most likely to reduce the frequency of these cramps?
A. Increasing the dialysate sodium concentration
B. Increasing the ultrafiltration rate
C. Administering intravenous albumin before dialysis
D. Switching to a higher efficiency dialyzer
Page 3
, Correct Answer: A. Increasing the dialysate sodium concentration
Rationale: Muscle cramps during hemodialysis are often due to rapid fluid and electrolyte shifts, particularly hyponatremia.
Increasing dialysate sodium concentration helps maintain serum sodium, reducing the osmotic shift and cramping. Increasing
ultrafiltration rate would worsen cramps. Albumin is not indicated. Higher efficiency dialyzer may increase solute removal and
exacerbate cramps.
Why Wrong:
B - Increasing ultrafiltration rate would remove fluid faster, potentially worsening cramps due to volume depletion.
C - Intravenous albumin is not standard for cramps; it is used for intradialytic hypotension in some cases.
D - Higher efficiency dialyzer may increase solute clearance, which could exacerbate electrolyte shifts and cramps.

Q4. Which of the following laboratory findings is most consistent with a diagnosis of renal tubular acidosis
type 1 (distal RTA)?
A. Hyperkalemia, normal anion gap metabolic acidosis, and alkaline urine (pH >5.5)
B. Hypokalemia, normal anion gap metabolic acidosis, and alkaline urine (pH >5.5)
C. Hyperkalemia, high anion gap metabolic acidosis, and acidic urine (pH <5.5)
D. Hypokalemia, high anion gap metabolic acidosis, and acidic urine (pH <5.5)
Correct Answer: B. Hypokalemia, normal anion gap metabolic acidosis, and alkaline urine (pH >5.5)
Rationale: Distal RTA (type 1) is characterized by a defect in hydrogen ion secretion in the collecting duct, leading
to an inability to acidify urine (urine pH >5.5) despite systemic acidosis. This results in hypokalemia due to
compensatory potassium wasting, and a normal anion gap metabolic acidosis. Hyperkalemia is seen in type 4 RTA.
High anion gap acidosis is not typical of RTA.
Why Wrong:
A - Hyperkalemia is not typical of distal RTA; it is associated with type 4 RTA.
C - High anion gap metabolic acidosis is not typical of RTA; RTA causes normal anion gap. Acidic urine
would indicate ability to acidify, which is impaired in distal RTA.
D - High anion gap is not typical; acidic urine is not consistent with distal RTA.

Acid-Base and Electrolyte Disorders, 6th Ed.
Q5. A patient with a history of recurrent calcium oxalate kidney stones is found to have hypercalciuria and a
urine pH of 6.5. Which of the following therapeutic agents is most appropriate to reduce stone recurrence?
A. Allopurinol
B. Thiazide diuretic
C. Potassium citrate
D. Acetazolamide
Correct Answer: B. Thiazide diuretic
Rationale: Thiazide diuretics reduce calcium excretion by increasing distal tubular calcium reabsorption, thereby
lowering urinary calcium and the risk of calcium oxalate stones. Allopurinol is for hyperuricosuria. Potassium
citrate is used to alkalinize urine in uric acid stones, but here urine pH is already 6.5 (slightly acidic) and the goal
is to reduce calcium excretion, not alkalinize. Acetazolamide would alkalinize urine but increase calcium excretion,
worsening stones.
Why Wrong:
A - Allopurinol is indicated for hyperuricosuric calcium oxalate stones, but the patient has hypercalciuria, not
hyperuricosuria.
C - Potassium citrate is used to alkalinize urine in uric acid or cystine stones; it may increase calcium
phosphate stone risk if urine pH becomes too high.
D - Acetazolamide causes metabolic acidosis and increases urinary calcium excretion, which would worsen
stone formation.
